The Study on City Gas Network Resisting Engineering Geological Hazard Damage Early Warning and Decision Support System

In this paper, using the secondary development function of Map GIS, we have established the city gas network resisting engineering geological hazard damage early warning and decision support system. The purpose of establishing this system is to supply model support, technical support and decision support to the early warning of engineering geological hazard damage to city gas network, anti-disaster capacity assessment and preventive measures and emergency plans development.
